++====== __Enable Motion Profile (**EM**)__ ======
++{{html clean="false" wiki="true"}}
++<div class="cmdcnt"><div class="cmdpad"></div><div class="cmdtxt">
++EM1 (Enable Motion Profile #1) is the default mode of the LSS and is an easy way to control the servo's position with a single (serial) position command. This mode uses a trapezoidal motion profile which takes care of acceleration, constant speed travel and deceleration. Once the actual position is within a certain value of the target, it switches to a holding algorithm. The LSS commands for Angular Acceleration and Deceleration (AA/CAA/AD/CAD) Angular Stiffness (AS/CAS) and Angular holding stiffness (AH/CAH) affect this motion profile. Modifiers like SD/S and T can be used in EM1.<div class="wikimodel-emptyline"></div>
--Example: #5O2400<cr>This command allows you to change the origin of the servo in relation to the factory zero position for that session. As with all action commands, the setting will be lost upon servo reset / power cycle. Origin offset commands are not cumulative and always relate to factory zero. In the first image, the origin at factory offset '0' (centered).

++This command enables a trapezoidal motion profile for servo #5 <div class="wikimodel-emptyline"></div>
++Ex: #5EM0&lt;cr&gt;<div class="wikimodel-emptyline"></div>
--In the second image, the origin, and the corresponding angular range (explained below) have been shifted by +240.0 degrees:
++This command will disable the built-in trapezoidal motion profile. As such, the servo will move at full speed to the target position using the D/MD action commands. Modifiers like SD/S or T cannot be used in EM0 mode. By default the Filter Position Counter, or "FPC" is active in EM0 mode to smooth out its operation. EM0 is suggested for applications where an external controller will be determining all incremental intermediate positions of the servo's motion, effectively replacing a trajectory manager. To prevent having to send position commands continuously to reach the desired position in EM0/FPC active (FPC >= 2), an internal position engine (IPE) repeats the last position command. Note that in EM0 mode, the servo will effectively always be in status: Holding (if using the query status command).

++====== __Filter Position Count (**FPC**)__ ======
++
++{{html clean="false" wiki="true"}}
++<div class="cmdcnt"><div class="cmdpad"></div><div class="cmdtxt">
++The FPC value relates to the depth of a first order filter (exponential weighted average) over the position change. This has the effect of slowing down both acceleration and deceleration while still allowing the LSS to try to reach the desired position at maximum power at all times. A smaller FPC value will reduce the smoothing effect and a larger value will increase it. To prevent having to send position commands continuously to reach the desired position in EM0/FPC active (FPC >= 2), an internal position engine (IPE) has been put in place, which is also active by default.

++====== __Angular Stiffness (**AS**)__ ======
--This command allows you to change the total angular range of the servo in tenths of degrees in EEPROM. The setting will be saved upon servo reset / power cycle.

++<div class="cmdcnt"><div class="cmdpad"></div><div class="cmdtxt">
++The servo's rigidity / angular stiffness can be thought of as (though not identical to) a damped spring in which the value affects the stiffness and embodies how much, and how quickly the servo tried keep the requested position against changes. There are no units.<div class="wikimodel-emptyline"></div>
++A higher value of "angular stiffness":<div class="wikimodel-emptyline"></div>
++
++* The more torque will be applied to try to keep the desired position against external input / changes
++* The faster the motor will reach its intended travel speed and the motor will decelerate faster and nearer to its target position<div class="wikimodel-emptyline"></div>
++
++A lower value on the other hand:<div class="wikimodel-emptyline"></div>
++
++* Causes a slower acceleration to the travel speed, and a slower deceleration
++* Allows the target position to deviate more from its position before additional torque is applied to bring it back<div class="wikimodel-emptyline"></div>
++
++The default value for stiffness depending on the firmware may be 0 or 1. Greater values produce increasingly erratic behavior and the effect becomes extreme below -4 and above +4. Maximum values are -10 to +10.<div class="wikimodel-emptyline"></div>
++
++Ex: #5AS-2&lt;cr&gt;<div class="wikimodel-emptyline"></div>
++
++This reduces the angular stiffness to -2 for that session, allowing the servo to deviate more around the desired position. This can be beneficial in many situations such as impacts (legged robots) where more of a "spring" effect is desired.

--Configure Speed in Degrees (**CSD**)Ex: #5CSD1800<cr>Using the CSD command sets the servo's maximum speed which is saved in EEPROM. In the example above, the servo's maximum speed will be set to 180.0 degrees per second. When the servo is powered on (or after a reset), the CSD value is used. Note that CSD and CSR (described below) are effectively the same, but allow the user to specify the speed in either unit. The last command (either CSR or CSD) is what the servo uses for that session.

  ====== __Maximum Speed in RPM (**SR**)__ ======
--Ex: #5SR45<cr>This command sets the servo's maximum speed for motion commands in rpm for that session. In the example above, the servo's maximum speed for that session would be set to 45rpm. The servo's maximum speed cannot be set higher than its physical limit at a given voltage. SR overrides CSR (described below) for that session. Upon reset or power cycle, the servo reverts to the value associated with CSR as described below. Note that SD (described above) and SR are effectively the same, but allow the user to specify the speed in either unit. The last command (either SR or SD) received is what the servo uses for that session.Query Speed in RPM (**QSR**)Ex: #5QSR<cr> might return *5QSR45<cr>By default QSR will return the current session value, which is set to the value of CSR as reset/power cycle and changed whenever an SD/SR command is processed. If #5QSR1<cr> is sent, the configured maximum speed (CSR value) will be returned instead. You can also query the current speed using "2" and the current target travel speed using "3". See the table below for an example:
